To all whom, it may concern,.-

Be it known that we, CHARLES PICKRING, machinist, and PETER CLARKE,mechanical engineer, of the city of Toronto, in the county of York andProvince of Ontario, Canada, have invented a certain new and ImprovedSander for Rollin g-Stock, of which the follow ing is a speciiication.

The object of our invention is to provide a device for sanding railswhich will be perfectly reliable and economical and subject to none ofthe disabilities under which Sanders labor which are provided withvalves of various kinds; and it consists, essentially, of a box providedwith an outlet-pipe having one or more openings therein above the bottomand a slide-pipe suitably guided and vertically movable, so that it maybe caused to cut off the sand from the opening in the outlet-pipe or topermit it to pass freely through the same, the whole being constructedin detail substantially as hereinafter more specifically described andthen deinitely claimed,

Figure l is a vertical sectional elevation of our improved sander withthe slide-pipe down. Fig. 2 is an enlarged perspective detail, partlybroken away, showing the outlet-pipe and the lower ends of the guard andslide pipes, with the latter in its raised position.

In the drawings like letters of reference indicate corresponding partsin both figures.

A is the sand-box, formed of sheet metal or other suitable material.Through the bottom of this box extends the outlet-pipe B, which ispreferablysecured to the metal plate a. In the sides of this pipe, ashort distance above the bottom ot the sand-box, are formed one or moreholes b. Surrounding the out-A let-pipe B is the slide-pipe C. Outsidethe slide-pipe is located the guard-pipe D. The upper end of thisguard-pipe is preferably connected to the cross-bar E, which is suitablysecured to the sides of the sander. The guard-pipe extends downwardly toa point near the opening in the outlet-pipe, but above the saine.

F is a vertical rod secured within the end of the slide-pipe C by meansof a pin c. The upper end of this vertical rod is pivoted to the innerend of the lever G, which is fulcrulned at d upon a suitable bearingextending upwardly from the crossbar E. The other end of this lever ispivotally connected with the vertical rod H, which extends upwardly to apoint convenient to the operators hand and is preferably provided with asuitable head or button. The lower end of this rod extends through thefloor I and is pivotally connected with the lever J, fulcruined at c ona suitable bearing secured below the fioor.

K is a foot-plunger projecting up through the floor of the car andprovided with a suitable head for engagement by the foot of theoperator. The lower end of this plunger is pivoted to the lever J. Bypressing with the foot upon the upper end of the plunger it is evidentthat the slide-pipe C may be raised to the position shown in Fig. 2. Thesand within the box will then run freely through the holes b and outthrough the pipe BI. The sand may be allowed either to drop directlythrough this pipe or a suitable convey'er may be connected thereto by aproper coupling.

L is a spring the upper end of which is secured in any suitable mannerto the rod F, preferably by being hooked over a pin passing through ahole therein. The lower end of this spring is hooked over a pin f,passing from side to side of the pipe D to one side of the rod F. Thisspring is in a state of tension and tends normally to maintain theslide-pipe in the position shown in Fig. l. We do not wish to confineourselves to the exact arrangement of this spring nor of the mechanismfor operating the vertical rod F, as many variations might be devisedwhich would not depart from the spirit of our invention.

When the slide-pipe C has been raised, as previously described, thespring L will promptly return it to its normal position, when the rod His released, with its lower edge in contact with the metal plate onorthe bottom of the box if the plate be located outside the same.

' It will be noted that the lower edge of the pipe C is sharpened, sothat it will the more readily penetrate the sand when pressed downwardwith the spring. When the parts v are in the position shown in Fig. l,it is found practically impossible for any of the sand in the box torise up within the pipe Gand How out through the hole b. l The lower endof the pipe should preferably make a tight lit upon the plate a, andeven if it did not it is found that sand has very little tendency torise up through any opening located below its surface. In other words,itwill not seek its level, as water does. Leakage of sand is thusabsolutely prevented by our device, and yet at the same time by pressureof the foot or hand the slide-pipe is quickly raised and a steady streamof sand will flow outward to the rail. When the pressure is removed, thespring L instantly stops the iiow.

The guard-pipe D is a very important part of our invention and, indeed,is essential if there be a great depth of sand in the sandbox. By itsuse the pressure and friction of the sand are taken off the slide-pipe,except at such parts as are necessarily exposed to enable lit tooperate. This enables the device to be worked with very little power andinsures its always acting freely.

The outlet-pipe B is preferably continued up well within the slide-pipeto act as a guide; but it might in many cases be cut oft at the level ofthe lower portion of the holes b, the sand then flowing down its openend.

It should be noted that in practice we make the levers G and .I doubleand pivot the vertical rods F and H between them. A weight might also insome cases be substituted for the spring L. The top of the box may beeither 'flat or sloped, as desired, and the upper portion of the box,above the cross-bar E, is preferably slotted for the passage of thelever G.

If both rails are to be sanded, we may place a V-coupling M on the lowerend of the pipe B, or if nccessarya sander might be used for each railand means provided for operating them simultaneously.

From the above description it will be seen that our invention is verysimple and cheap, as there can be no waste, that it may be operatedwithout the users attention being directed away from his other work,that it is absolutely impossible for the parts to stick or cut, asalways happens with ordinary sandervalves, and that it will be perfectlyreliable under all conditions of use.

What we claimas our invention is l.

and a suitably-supported guard-pipe surrounding the said slide-pipe anddescending to a point near the opening in the outlet-pipe but above thesame, substantially as and for the purpose specified.
